Based on the images taken through Stella’s microscope, which cell structures could be clearly identified using a compound microscope?
Answers
Cell structures could be clearly seen using a 400x compound microscope, you could see how it is stuctured and detailed because of the magnification, you can see the cell at 40x but not as clear as you can with 400x

How does this image compare to the white blood cells you saw using Stella’s compound microscope? What are the pros and cons of using electron and compound microscopes? In your response consider cost and ease of use.
Answers
Answer:
The Resolution and Magnify power are the major differences between the electron microscope compare to compound microscope. This is due to the source of power for the operation,Light rays of (400-700nm) are used by the compound microscopes,while short frequencies beam of electrons of( 1 nm)are used by the Electron Microscope.
The compound microscope consists of objective lens with short focal length.They are therefore used for magnification of tiny objects.While the E. microscope makes use of beam of electrons(compare to light rays in the compound microscope) with higher resolutions.The beam of electrons are focused by magnetic lenses to give images.
Electron microscope is cumbersome to use,it is expensive, requires a lot of expertise, and occupies large space.
Compound are less expensive with low maintenance,it does not requires expertise;very easy to operate, and can easily be moved about.
There is low risk of radiation with compound,lower magnification,both dead and living creatures can be used.
E.microscope,has high radiation risk,higher magnification, with only dead materials.
Explanation:
White blood cells are the immune cells that protect the body. They are also known as leukocytes or leucocytes.
The compound microscope magnifies objects lesser than the electron microscope. We can see higher magnified things in the electron microscope.
Pros and cons of electron and compound microscopeCompound microscopes are easier to move and set up because they are small and light.Electron microscopes are heavy and higher. They are harder to set up and move.Electron microscopes use electromagnet glasses, whereas compound microscopes use glass lenses.Compound microscopes are cheaper than electron microscopes.Thus, these are the pros and cons of Compound microscopes and Electron microscopes.

Which specialized carbohydrate is used in shrimp exoskeletons?
Answers
Answer:
A specialized carbohydrate that is used for structure in shrimp is called chitin. Not only it is found in the shrimp cells, but also on other crustaceans such as crabs and lobsters. Chitin is a derivative of glucose and a characteristic element in the exoskeletons of crustaceans, cell walls of fungi, internal shells of squids and octopuses, and scales of fish.
Explanation:
The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
An exoskeleton refers to an external skeleton that protects and supports the body of an animal. The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
Chitin is a fibrous substance that's made up of polysaccharides. It's the major constituent in the exoskeleton of arthropods. Chitin can also be found in crustaceans. It is a derivative of glucose.

Answers
Answer:
Genes
Explanation:
Gregor Mendel discovered in his experiments that a factor determined the physical characteristics of an organism. This factor is called a gene. A gene is the molecular unit of heredity in a living organism.
Genes are segments of DNA that holds the information needed to build and maintain an organism and pass genetic traits to offspring. The trait of an organism, which refers to the physical characteristics of an organism, are passed from parents to offsprings via genes. The genes also contain variant forms called ALLELE that determines which trait an organism will possess.

Binary fission occurs in which of the following type of organsim?
Answers
Answer:
A. Prokaryotes like bacteria
Explanation:
Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).
Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.
The answer is thus A.

(604 (1) 0 + 111e13) và (O2 + CK Og
Where is the energy shown in the equation transferred as a result of photosynthesis?
into water
into the air
into sugars
into the ground
Answers
Answer:
The chemical equation of Photosynthesis in the question is not clear but the energy goes into water.
The answer is "Into Water"
Explanation:
Photosynthesis is a metabolic reaction which involves the synthesis of sugars (Glucose) in plants using carbondioxide and water input in the presence of sunlight. Photosynthesis, which occurs in the Chloroplast of plant cells, occurs in two stages viz: light dependent stage and light-independent stage.
The light dependent stage involves the production of ATP and NADPH molecules, which will be used in the light-independent stage. The chemical equation of photosynthesis is as follows:
6CO2 + 6H2O ---light energy--> C6H12O6 + 6O2
The light energy input in this reaction (from sunlight) is used in the light-dependent stage to break down water molecules, a process called PHOTOLYSIS OF WATER. The photolysis of water releases electrons and protons used to build a proton pump for the synthesis of ATP.
Therefore, the energy input from photosynthetic process goes into water.

Categorize Different Foods Categorize the food items below by selecting which macromolecule they are known to contain. apple steak celery olive oil potato avocado egg
Answers
Answer:
The correct categorization of the listed food items would be:
Carbohydrate: apple, celery, potato
Protein: Steak, egg,
Fat: Olive oil, avocado.
The four major macromolecules are carbohydrates, proteins, lipids, and nucleic acids.
Foods like apple, celery, and potato are rich in carbohydrates.
Foods like chicken, meat, eggs, et cetera are rich in proteins.
Similarly, foods like olive oil, mustard oil, butter, et cetera are rich in fats or lipids.
Explanation:
Answer: apple- carb; steak- protein; celery- carb; olive oil- lipid; potato- carb; avocado- lipid; egg- protein
Explanation:
Fruit and veggies are mainly made of carbohydrates because that is the storage and structural components they use (think glucose, cellulose, starch, etc.); Steak is a meat, and meat is technically muscle- muscle is built from protein; Olive oil and avocado are lipids because they are considered fats; Egg is protein because it is an animal by-product, and contains many amino acids, which build up proteins.

Answer:
B) Violet and blue light by chlorophyl a and orange, and red light by chlorophyl B
Explanation:
Chlorophyll is the pigment present in green plants which is used in the process of photosynthesis by trapping solar energy for use. Chlorophyll comprises of two types namely: Chlorophyll A and Chlorophyll B
Chlorophyll A is known to absorb light in the blue-violet region while chlorophyll B absorbs light in red-blue region. These pigments however don’t absorb green light but they instead reflect it. This makes option C and D invalid. The closest option in their properties is however B.

What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.
Answers
Answer:
The body would break down existing muscle to get the amino acids it needs.
Explanation:
If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
What is the function of proteins?Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.
Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
